Licensed ag lime producers must sample/analyze each ag lime product each year. The analysis provides the ag lime quality rating expressed in the minimum pounds of ENP per Ton (Min. lbs ENP/Ton). The Min. lbs ENP/Ton must be listed on the ag lime product distribution label.
What is agricultural lime?
Ag Lime Analysis Results The analysis results are provided as an educational/information component of the MDA's ag lime program. The analysis results were submitted by ag lime Producers either per samples analyzed by the University of Minnesota Soil Testing Laboratory or by Producers certified by the MDA to analyze their own ag lime products.
What is AGAG lime?
Periodically, agricultural limestone (ag lime) is needed to neutralize soil acidity and maintain crop productivity. Ag lime replaces exchangeable acidic ions, such as hydrogen ions, with calcium (Ca 2+) and some magnesium (Mg 2+) ions, which are considered basic (Figure 1). The chemical reactions that take place in soil when lime
What are the limitations of AG lime?
Ag lime (CaCO 3) is the most common material because it is affordable, effective, and relatively easy to apply. The effectiveness of ag lime is dependent upon the purity and the fineness of the product. Impurities in the ag lime, such as clay and sand, significantly reduce the effectiveness of the product. ... Analysis of liming materials can provide an index of the effectiveness of the …
What is the difference between agricultural lime and dolomitic lime?
04/04/2017 · Agricultural Lime. Often referred to as “aglime“, agricultural lime is simply limestone that has been pulverized down to a fine particle size and introduced to acidic soil. Lime is selected because it contains such a high amount of calcium, which works to neutralize the soil’s pH levels.
What is lime analysis?
“Available lime index,” expressed as a percentage of calcium oxide, is a measure of the alkaline content of high calcium quicklime and hydrated lime that reacts with hydrochloric acid under the specific conditions described in this method.
What does ag lime contain?
Agricultural lime (calcium carbonate) This is the most commonly used liming material on the North Coast. It consists of limestone crushed to a fine powder and is usually the cheapest material for correcting soil acidity. Good quality lime has 37–40% calcium.
How much calcium is in ag lime?

What is the difference between ag lime and pelletized lime?
When comparing pelletized lime vs. ag lime, the characteristic that most divides the two products is application handling. While pelletized lime is easily spread with most spreaders, ag lime requires a specialty spreader.
Will ag lime dry up mud?
You don't want to dig up the mud and cart it away--too expensive and disruptive. LIME IS THE ANSWER! of either quicklime or hydrated lime, dries up wet soil quickly, so that it can be compacted readily, forming a working table that will resist further wetting as well--you can get back to work!
How fast does ag lime work?
How long will it take for lime to react with the soil and how long will it last? Lime will react completely with the soil in two to three years after it has been applied; although, benefits from lime may occur within the first few months after application.09-Nov-2015
What is the neutralizing value of lime for agricultural lime?
90 percentThe actual rate of a liming material to be applied can then be calculated from the soil-test recommendation, assuming that standard agricultural lime has an effective neutralizing value of 90 percent (0.9).12-Dec-2018
Does ag lime dissolve in water?
Unlike quicklime and slaked lime, ground agricultural limestone is not very soluble. This results in the need for more agricultural lime to be added to the pond to achieve an effect on its chemistry. Two or more tons of agricultural limestone per acre are generally applied to low alkalinity ponds.31-Aug-2018
How many pounds of lime do you need per acre?
A “1:10 ratio” rule of thumb has been promoted for comparing the short-term neutralizing effectiveness of pelletized lime to agricultural lime. (Example: if a soil test recommends the ENM equivalent of 2000 lbs of agricultural lime per acre apply 200 lbs of pelletized lime/acre).
Is pellet lime stronger than ag lime?
Pelletized lime is typically finer than ag-lime, so its ENP value may be higher, meaning that it takes less pelletized lime to neutralize the same level of soil acidity.26-Feb-2007
How long does it take for pelletized lime to break down?
That's because the amount of time that it will take to raise your soil pH depends on just how low it was. Generally speaking, it could take one to two years. It takes a full year for lime for lawns to completely break down.
Do you need less pelletized lime?
As in the case of aglime, pelletized lime is used to raise the pH levels of soil, in order to accommodate plant life. One advantage of pelletized lime is that less material is required to balance the soil than traditional aglime (at a ratio difference of 1:10).05-May-2017
